Naproxen-induced toxicosis in a dog

Naproxen, a nonsteroidal anti-inflammatory drug, induced gastric ulceration and bleeding in a dog. Clinical signs included vomiting, anemia, melena, and weakness. The dog responded to a blood transfusion and supportive treatment (lactated Ringer's solution with added K+ and B vitamins, an antacid, and cimetidine). Naproxen had been given to the dog by the owner, as treatment for shoulder stiffness.     

Ureterocolonic anastomosis in a dog with transitional cell carcinoma of the urinary bladder

Ureterocolonic anastomosis and cystectomy were performed in a dog for treatment of transitional cell carcinoma of the urinary bladder. The dog remained an acceptable house pet for 10 months after surgery. However, the tumor recurred 10 months after surgery, and the dog was euthanatized. Our results indicated that the combination of ureterocolonic anastomosis and cystectomy can be an acceptable form of palliative treatment for transitional cell carcinoma of the urinary bladder in the dog.

Colonic perforation after corticosteroid and surgical treatment of intervertebral disk disease in a dog

Colonic perforation after corticosteroid and surgical treatment of intervertebral disk disease in a dog Perforation of the distal segment of the descending colon, after corticosteroid and neurosurgical treatment for an intervertebral disk herniation, resulted in the death of a 3-year-old, male, Lhasa Apso. Initially, the dog was paraparetic in the hindlimbs, but became paraplegic after 4 days of conservative treatment. Corticosteroids were administered before referral and during decompressive hemilaminectomy. Six days after surgery, the dog had improved neurologically, but was depressed, anorectic, and vomiting. Abdominocentesis revealed septic peritonitis. The dog died shortly after a perforation in the descending colon was surgically corrected.     

Infection with Basidiobolus ranarum in two dogs

Basidiobolus ranarum is a saprophytic fungus in the environment that also is a part of the endogenous microflora in the gastrointestinal tract of several vertebrates. These organisms may penetrate skin or muscosa of humans and other animals, causing granulomatous inflammation. Two dogs infected with B. ranarum had prolonged or repeated exposure to water or soil in their environment. One dog had progressive subcutaneous infection of all the limbs, and the other dog had recurrent coughing and dyspnea caused by tracheobronchitis. In both dogs, secondary bacterial infection of the lesions was evident. Treatment of the dog with subcutaneous infection involved cutaneous dressings and sequential use of enrofloxacin and itraconazole; however, this resulted in suspected liver damage without clinical improvement. Subsequent treatment with potassium iodide and a lipid formulation of amphotericin B was also unsuccessful, and the dog was euthanatized. The other dog was treated alternately with enrofloxacin and itraconazole. When the clinical signs and infection returned, combination treatment with both drugs was more effective; however, the dog developed liver damage. Subsequent treatment with enrofloxacin on an intermittent basis controlled the dog's coughing during a 3-year period.     

Thoracic, Abdominal and Vertebral Actinomycosis

The clinical, laboratory, radiographic, and histologic features and the response to therapy in three dogs with actinomycosis are reported. One dog (dog 1) had a 12-cm nonresectable mass extending from the ventrolateral chest wall into the left ventricular myocardium. Another dog (dog 2) had a diffuse peritonitis with "sulfur granules" and two large masses. One of these masses was nonresectable involving adjacent abdominal structures. A third dog (dog 3) had a subvertebral mass at T1-3 producing quadraplegia. Two dogs had periosteal reactions involving adjacent sternebrae (dog 1) or ribs and vertebral bodies (dog 3) that are characteristic of Actinomyces spp infections. In dogs 1 and 2 the diagnosis was based on the morphologic and tinctorial properties of free sulfur granules and/or tissue granules. Culture results were variable. Tissue from dog 1 yielded no growth, while polymicrobial infections, which included Actinomyces spp, were identified in dogs 2 and 3. Actinomyces odontolyticus was isolated from dog 3. Although the actinomycotic granulomas were either not excised or only partially excised from dogs 1 and 2, both animals were cured by the oral administration of high doses of penicillin G for 19 and 6 months, respectively. Dog 3 responded dramatically to the same antibiotic therapy given for 5 months. However, within 4 months of discontinuing treatment an abscess and draining fistulous tracts developed in the left axillary region. Two surgical fistulectomies and additional penicillin therapy were required to cure this animal. These cases and the current veterinary and human literature on actinomycosis are used to propose a rational approach to the treatment of actinomycosis in the dog.     

Use of Ursodeoxycholic Acids in a Dog With Chronic Hepatitis: Effects on Serum Hepatic Tests and Endogenous Bile Acid Composition

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.     

Sulphanilamide toxicity and crystalluria in a dog after suspected ingestion of a wound treatment ointment

A dog was presented in a comatose state with spastic convulsions. Five to six hours before admission the dog had been in a stableyard for some time. The dog recovered within three days, after symptomatic treatment with barbiturates and sodium bicarbonate. During the first day of observation, urinary examination revealed crystalluria, and the urinary precipitate consisted of sulphanilamide as identified by mass and infrared spectrometry. Sulphanilamide toxicity was diagnosed on the basis of the neurological disturbances and the concomitant presence of sulphanilamide crystals in the urine. The most plausible explanation of the accidental poisoning and unusual case of crystalluria was ingestion of a sulphanilamide-containing ointment used in the topical treatment of wounds and fetlock eczema in horses, to which the dog had access.     

Osteosarcoma of the patella in a dog

Osteosarcoma of the patella was diagnosed by biopsy in a 9-year-old, male dog of mixed breeding. The dog was originally examined because of intermittent lameness of the left hindlimb; there were minimal palpable abnormalities of the stifle. After the diagnosis, the owner refused further treatment for the dog. The dog was reexamined 13 months later because of a marked swelling of the stifle. The dog was euthanatized and necropsy findings confirmed the diagnosis.     

Successful outcome after a single endoscopic fecal microbiota transplantation in a Shiba dog with non-responsive enteropathy during the treatment with chlorambucil

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.     

Acute pulmonary edema in a dog with severe pulmonary valve stenosis: A rare complication after balloon valvuloplasty

Pulmonic stenosis is a frequent congenital heart disease in dogs, and the treatment of choice is balloon valvuloplasty which is usually safe and successful. The authors describe for the first time a severe complication after balloon valvuloplasty in a five-month-old dog. After effective treatment, with a considerable drop in right ventricular pressures, the dog developed hypoxemia and dyspnea due to pulmonary edema. The dog underwent intensive care and symptoms improved after a few hours of oxygen therapy, continuous positive airway pressure, and furosemide. Although this event is rare, it could have a large impact on patient survival and should be considered in the treatment of severe pulmonary valve stenosis in the future.     

Nonweightbearing lameness secondary to synovial sarcoma in a young dog

Synovial sarcoma was diagnosed in the right carpus of a 2 1/2-year-old mixed-breed dog. The dog had developed a right forelimb lameness before one year of age. The lameness was progressive for nearly 2 years, resulting in severe disuse atrophy of the right forelimb musculature and pronounced osteopenia. A definitive diagnosis was not made until the dog was referred after 2 years of conservative treatment was ineffectual. Right forelimb amputation was done and the dog survived an additional 15 months. The protracted clinical course before definitive diagnosis underscores the need for aggressive pursuit of a diagnosis when conservative treatment of a lameness is not efficacious.     

Sinus mucocele secondary to craniofacial trauma in a dog

A sinsus mucocele formed in the frontal sinus of a dog secondary to obstruction of the nasofrontal opening. The dog was successfully treated by surgical enlargement of the nasofrontal opening, curettage of the sinus epithelium, and placement of a fat graft and drain in the sinus. Although mucocele formation is uncommon in animals, it should be considered as a differential diagnosis for masses of the sinonasal area. Characteristic radiographic and cytologic findings should alert the clinician to this diagnosis, and along with aggressive treatment, should shorten the diagnostic and treatment delay experienced by the dog in this report.     

Neurologic complications following treatment of canine hypoadrenocorticism

After treatment for hypoadrenocorticism, an 18-month-old dog exhibited marked ataxia and intermittent muscle tremors, progressing to head pressing, dysphagia, and quadraparesis. Serum sodium increased by 38.9 mmol in 48 hours, suggesting myelinolysis. The dog made a complete recovery after intensive treatment.     

Fatal thrombocytopenic hemorrhagic diathesis associated with dapsone administration to a dog

Dapsone was given for six days to a dog with chronic skin disease. The dog then became weak and anorectic, and it vomited and had purpura caused by severe thrombocytopenic hemorrhagic diathesis. Despite treatment, the dog died a week later. There were clinical and pathologic evidence that the dog's platelets and megakaryocytes had been destroyed during the first few days of dapsone therapy. It was concluded that the syndrome was dapsone-induced and that thrombocytopenia should be considered among the adverse reactions to dapsone in the dog.     

Corrective osteotomy for bilateral forelimb varus deformities in a working dog

Bilateral varus antebrachial deformity in a 7-month-old working dog was surgically corrected. The deformity was a sequela to premature closure of the distal radial physes after trauma to the forelimbs. Treatment was by ulnectomy and oblique radial osteotomy. Stabilisation of the fractures was maintained by an external fixation device. The treatment was successful and the dog returned to work as a sheep dog.

犬血丝虫病诊疗病例

犬血丝虫病是由犬血丝虫寄生于犬类动物右心室或肺动脉引起的犬类动物的一种重要的寄生虫病,以循环障碍、呼吸困难、贫血为主要特征。犬血丝虫又叫犬心丝虫或犬恶丝虫,犬为其终末宿主,蚊、蚤等吸血昆虫是中间宿主。当寄生的虫体影响心脏器质功能（比如三尖瓣或肺动脉瓣功能不全）时,患犬会出现呼吸困难、胸腹水、下体浮肿等较为严重的临床症状,甚至发生急性死亡。诊断本病以外周血中查到犬血丝虫的幼虫微丝蚴为主。治疗本病则以驱虫为主,补血、输液等对症治疗作为辅助措施。     

Staphylococcus pseudintermedius infection associated with nodular skin lesions and systemic inflammatory response syndrome in a dog

A 10-year-old Pekingese dog with atopic dermatitis was referred due to pyrexia, multiple skin nodules, anorexia, and depression. The dog was diagnosed as having systemic inflammatory response syndrome (SIRS) induced by bacterial dermatitis. This case presents diagnosis and treatment of SIRS with staphylococcal skin infection in a dog that was immunosuppressed due to long-term use of corticosteroid.
