A 10-year-old, intact male Siberian husky dog was presented for a suspected left renal cyst. Computed tomography (CT) identified a large, left kidney mass with retroperitoneal hemorrhage. A left-sided nephrectomy was performed, and histopathology confirmed a renal plasmacytoma. Perioperative screening for multiple myeloma was negative. The dog was lost to follow-up and was euthanized 11 months after surgery. A necropsy was not performed. To the authors’ knowledge, this is the first case of renal extramedullary plasmacytoma in a dog.Key clinical message:This report describes the clinical presentation, and laboratory, diagnostic imaging, and surgery findings of a case of renal extramedullary plasmacytoma in a dog.  相似文献

An 11-month-old, neutered female miniature schnauzer presented with a severe head injury. The dog was treated for the acute effects of craniocerebral trauma and was hospitalized for just over a week. Several weeks later, she became weak and lethargic. A diagnosis of hypoadrenocorticism was confirmed with an adrenocorticotropin hormone (ACTH) stimulation test. An endogenous ACTH assay confirmed secondary hypoadrenocorticism. The dog was tested for hypopituitarism with canine thyroid-stimulating hormone and thyroxine serum assays and an insulin-like growth factor assay. These tests could not confirm panhypopituitarism in this dog. The hypoadrenocorticism was treated with prednisone, and the dog remains controlled adequately three years later.  相似文献

A 7-year 6-month-old, castrated male Shiba dog presented with a 1-month history of lethargy, anorexia, vomiting, and frequent watery diarrhea. Weight loss, hypoalbuminemia, anemia, and leukocytosis were detected at the first visit. The dog was diagnosed with non-responsive enteropathy (NRE) based on clinical and histopathological examinations. Since the dog did not respond to the immunosuppressive drugs, fecal microbiota transplantation (FMT) was performed during the treatment with chlorambucil. A single endoscopic FMT into the cecum and colon drastically recovered clinical signs and clinicopathological abnormalities and corrected dysbiosis in the dog. No recurrence or adverse events were observed. The present case report suggests that FMT, possibly together with chlorambucil, might be a treatment option for NRE in Shiba dogs that have poorer prognosis compared with other dog breeds.  相似文献

An incomplete atrioventricular (AV) canal with bidirectional shunting and cardiac tamponade in a 6-year-old dog was initially diagnosed echocardiographically as a common atrium. The dog failed to respond to medical therapy and was euthanized. Upon necropsy, the defect was confirmed as an incomplete AV canal. A mechanism for the potential sequence of clinical events demonstrated in this dog is proposed.  相似文献

Objective: To describe the surgical repair and pre‐ and postoperative management of a peritoneopericardial diaphragmatic hernia (PPDH) in a pregnant dog. Case summary: A pregnant dog was presented for vomiting, lethargy, and pale mucous membranes. Pulsus paradoxus was noted on physical examination. The dog was diagnosed with a PPDH via thoracic radiographs, abdominal ultrasound, and an echocardiogram. The hernia was surgically repaired and the dog received supportive medical care until the puppies were old enough to be delivered via cesarean section. The mother and all puppies survived. New or unique information provided: This is the first report that describes the surgical repair and postoperative management of a PPDH in a pregnant dog.  相似文献

A 5-year-old, 1.36-kg, neutered male Yorkshire terrier was referred for evaluation of a persistent right aortic arch with concurrent megaesophagus. The dog was 3 months old when clinical signs were first noted, 2 years of age when diagnosed with megaesophagus, and 4 years of age when diagnosed with vascular ring anomaly (VRA). Surgical correction of the VRA was performed when the dog was 5 years of age, after gastrostomy tube feeding for 1 year to maintain nutritional requirements and mitigate the degree and duration of the esophageal distention. Thirteen months after surgery, the dog was eating soft dog food with no vomiting or regurgitation.  相似文献

A case of stilboestrol toxicity is described in a dog which was treated for prostatic hyperplasia with stilboestrol dipropionate (10 mg) daily for 5 days. An initial anaemia and thrombocytopaenia of 19,500/microliters was recorded on day 11, and a severe leukocytosis of 125,300/microliters on day 15 was followed by a precipitous drop to 8,400/microliters on day 21. The dog received antibiotic treatment for concurrent peritonitis and prostatitis/cystitis between days 7 and 15. The dog died on day 41 with marrow aplasia.  相似文献

In vitro blastogenesis of dog and fox lymphocytes was compared by a microculture technique. The highest 3H-thymidine incorporation in cultures of dog lymphocytes was observed at day 3, while in those of fox at day 2, incubated either at 37 degrees C or at 39 degrees C. Lymphocytes cultured at 39 degrees C incorporated more tritiated thymidine than did cells cultured at 37 degrees C. The stimulation index (SI) of dog peripheral blood lymphocytes to both mitogens concanavalin A (Con A) and leucoagglutinin (LA) was in a similar range, while pokeweed mitogen (PWM) showed a weaker but significant stimulatory action. The blastogenesis of fox lymphocytes was the greatest in Con A stimulated cultures. The mitogenic potency of LA and PWM was about half of that of Con A, with no essential difference between them. Maximum lymphocyte proliferation of dog and fox was observed when culture media were supplemented with 10% fetal calf serum (FCS).  相似文献

Brain and ocular metastases from a transmissible venereal tumour in a dog   总被引:1,自引:0,他引:1  
A five-year-old crossbred dog was referred with rapidly growing masses over its penis and right popliteal lymph node. The dog had severe blepharospasm, congestion of episcleral vessels and rubeosis iridis of the left eye. A presumptive diagnosis of transmissible venereal tumour (TVT) and iridocyclitis was made based on the results of fine needle aspiration. Chemotherapy with vincristine and prednisolone was initiated and after four months the dog made a complete recovery. However, the dog subsequently relapsed, showing miosis, blepharospasm and a well defined mass within the anterior chamber of the left eye. In addition, the dog exhibited generalised 'grand mal' type seizures. Computed tomographic (CT) examination of the brain revealed two distinct masses in the left frontal lobe. Because of the poor prognosis, the owners elected to have the dog euthanased. On histopathology, metastases of TVT in the left eye and left cerebral hemisphere were found, showing no specific staining for CD3, immunoglobulin (Ig) G, IgM and lambda light chains. It was therefore concluded that the tumour growth was progressive, and that there was an absence of local humoral immune response against TVT in this case.  相似文献

The vitamin A concentration was determined in 89 Australian brands of commercial foods for dogs and cats. It was found that 8% of the dog foods and 14% of the cat foods had concentrations of vitamin A below the minimum recommended 1.1 mg/kg dry matter (dm) for dogs and 1.8 mg/kg dm for pregnant or lactating cats. Canned and fish-labelled cat foods were the only varieties with less than the minimum recommended concentration of Vitamin A, of which 71% were the same brand. The minimum recommended concentration of vitamin A was exceeded in all canned dog food tested. Concentrations of vitamin A in dry (ca. 6% moisture) dog and cat foods and semi-moist dog foods (ca. 23% moisture) never exceeded 10 mg vitamin A/kg dm. In contrast, canned pet foods stated to contain liver or kidney showed vitamin A concentrations from 13 to 284 mg/kg dm.  相似文献

A six-year-old, spayed female, cocker spaniel was presented for hypoglycemic seizures. Hypoglycemia with concomitant hyperinsulinemia suggested an insulin-secreting tumor. Pancreatic masses were resected, and insulinoma was diagnosed. Six weeks later, the dog presented in hyperinsulinemic-hypoglycemic crisis (HHC). The dog was initially stabilized with intravenous dextrose boluses and infusions, but seizure activity recurred and persisted. A glucagon constant-rate infusion (GCRI) was initiated, and neurological signs quickly resolved. Dextrose was withdrawn over 24 hours, and euglycemia was maintained by GCRI alone. Despite aggressive medical management including the use of prednisone, diazoxide, bovine somatotropin, and streptozocin, the dog presented on two subsequent occasions in HHC and both times was rapidly stabilized with GCRI alone. In this dog, GCRI was a fast, safe, and effective method of achieving and maintaining euglycemia despite intractable hyperinsulinism. The clinical use of GCRI merits further investigation for management of HHC in veterinary species.  相似文献

Abstract Objective: To report a life‐threatening complication (airway collapse) associated with a common procedure (anesthesia) and to describe its successful management. Case Summary: A dog without pre‐existing signs of respiratory disease developed hypoxemia and severe atelectasis in the post‐anesthetic recovery period and was demonstrated, by bronchoscopic examination, to have severe airway collapse. Mechanical ventilation was used to re‐expand collapsed lung units and to prevent re‐collapse. A ventilation strategy designed to minimize airway and alveolar trauma was used. The dog was successfully weaned from the ventilator and made a full recovery. Unique Information Provided: Acute, severe hypoxemia due to airway collapse occurred in the post‐operative period in a dog with no signs of pre‐existing respiratory disease. The dog was successfully managed with short‐term mechanical ventilation. High frequency jet ventilation was used for a diagnostic bronchoscopy.  相似文献

SUMMARY A survey of the attitudes of dog owners to desexing male and female dogs was conducted in the Brisbane area. Over 15800 replies (35% response) were returned for analyses and included both demographic and attitude data. The most common reasons given by owners for not having the dog desexed were that it was unnecessary or they wanted to breed from it or could not afford it or did not agree with it or that the dog was too old or it might get fat. Nearly twice as many male owners agreed that desexing male dogs removed maleness and also more males agreed with the question “Do you equate dog sexuality with human sexuality?” Female owners were more aware than males that their female dogs did not need to have a season (oestrus) or a litter before being desexed. More male owners thought that desexing changed a male or female dog's personality. A disturbing fact was that 61.1% of male owners and 47.3% of female owners would now not have their dog desexed if it had not already been done. More male than female dog owners were ignorant about whether desexing changed personality, made dogs frustrated, or if female dogs should have a season or a litter before desexing. The study showed a gender bias in owner attitudes to all the attitude questions.  相似文献

A large outbreak of canine salmonellosis in military watch dogs due to Salmonella Montevideo and/or Salmonella Give was only recognized through a monitoring program, implemented by the military forces. In 51 out of 80 exposed dogs (63.8%) from four kennels Salmonella was isolated from fecal samples. The prevalence per sampling day ranged from 5.6 to 77.8%. Clinical disease with mild diarrhea but without fever appeared only in nine dogs (11.3% of study population, 16.9% of cases) from one kennel (***P < 0.001). Risk analysis identified "dog food A" (odds ratio 3.33 [1.12 < OR < 10.06] *P < 0.05) and "dog food C" (odds ratio 3.40 [1.07 < OR < 11.22] *P < 0.05), two commercial dehydrated dog feeds, as suspected infectious sources. Feeding "dog food C" alone or together with "dog food A" was significantly associated with clinical disease (***P < 0.001). S. Montevideo and S. Give with similar plasmid profiles and PFGE-restriction patterns were isolated from the suspected dog feeds and fecal samples. This outbreak demonstrates not only that Salmonella infections in dogs occur without clinical symptoms but also that large outbreaks occur after feeding dehydrated dog feeds. Especially in households with known risk group patients this finding demonstrates a particular risk for their owners, as they often live in close contact with their animals.  相似文献

A dog with severe cholestasis secondary to chronic hepatitis was treated with ursodeoxycholic acid (UDCA1 PO. After 2 weeks of daily treatment, the dog was more active and had an improved appetite. Monthly serum biochemical determinations and analysis of individual bile acid profiles documented improvement in hepatobiliary tests and a marked reduction in the concentrations of potentially hepatotoxic endogenous bile acids. These effects were maintained for approximately 6 months- The findings in this dog are similar to those reported for human patients treated with UDCA and provide preliminary evidence in support of its continued evaluation in the treatment of cholestatic liver disease in the dog.  相似文献

Objective– To describe successful management of saltwater near-drowning in a dog using mechanical ventilation. Case Summary– A 7-year-old spayed female Golden Retriever weighing 37 kg was referred for mechanical ventilation after saltwater submersion injury. The dog had a history of rare seizures characterized by pre-ictal agitation. On the morning of the event, the dog became agitated and ran toward Puget Sound. The owners discovered the dog unconscious in approximately 25.4 cm (10 in) of water, with her head submerged. The owners estimated that the dog was submerged for approximately 30 seconds. The dog was presented immediately to the nearest emergency facility where initial diagnostic testing and treatment included venous blood gases, nasal oxygen, and IV fluids. The dog was dyspneic despite nasal oxygen administration and was referred for mechanical ventilation. Upon arrival the patient was cyanotic with an arterial partial pressure of oxygen of 38 mm Hg (reference interval 85–100 mm Hg) and oxygenation saturation of 62% (reference interval >95%). Thoracic radiographs were taken and revealed severe, bilateral pulmonary infiltrates. The patient was ventilated for 70 hours and was discharged 4 days later. Complications included pneumonia and phlebitis at the site of a cephalic IV catheter. Follow up thoracic radiographs 10 days after discharge were within normal limits and the owners report a full recovery at 1 year. New or Unique Information Provided– Submersion injury can result in acute respiratory distress syndrome in dogs. Mechanical ventilation provided critical support during pulmonary recovery in this dog.  相似文献

A 4-year-old Basque Shepherd male dog was presented for breeding soundness evaluation after the dog failed to impregnate the three bitches he had mated. Clinical examination showed no anomaly of the reproductive system. Semen evaluation showed normal sperm count (640 x 10(6)), 80% had progressively motile spermatozoa, and 96% had morphologically abnormal sperm of which 84% had proximal cytoplasmic droplet and 12% had proximal droplet plus other anomaly. A zona pellucida-binding assay, using canine oocytes derived from frozen-thawed ovaries, was performed in order to investigate the zona-binding ability of dog spermatozoa with proximal cytoplasmic droplets. For the zona pellucida-binding assay, ovaries were thawed and minced in phosphate-buffered saline + 0.4% bovine serum albumin, the oocytes recovered were divided into two groups of 35-40 oocytes to be, respectively, used with the infertile dog and with a control fertile dog. Spermatozoa were capacitated in Canine Capacitating Medium (CCM) at 38.5 degrees C and 5% CO(2) in air for 2 h before oocyte insemination. Groups of five to six oocytes placed in 45 microl droplets of CCM were incubated for 1 h. Afterwards, 5 microl of CCM containing 25,000 spermatozoa were added to each droplet and co-incubated for 2 h before fixation and evaluation of the complexes. After oocyte insemination, sperm motility and viability were evaluated: the sample from the infertile dog had 85% sperm motility with fast and linear progressive movement, and sperm viability of 92%. The sample from the control dog showed 40% sperm motility with fast and highly curvilinear and erratic movement, high degree of sperm agglutination and sperm viability of 32%. For the infertile dog the mean number of bound spermatozoa/oocyte was 0.33 whereas for the control dog it was 1.80. It was concluded that dog sperm with proximal cytoplasmic droplets seem to lack normal capacitating ability in vitro, and consequently, they may have reduced capacity to bind to the zona pellucida of canine oocytes.  相似文献

A 9-year-old golden retriever dog was evaluated for polyuria, polydipsia, weight loss, and elevated serum thyroxine. Targeted questioning revealed that the dog was coprophagic and routinely ingested the feces of a dog that was treated with twice-daily levothyroxine. Clinical signs resolved and serum thyroxine decreased to normal levels in the affected dog with prevention of coprophagy.  相似文献
