A dog with polyarthritis, angular joint deformities, and a high serum antinucleolar antibody titer was treated over a period of 20 months. During the clinical course, leukopenia, thrombocytopenia, Coombs' positive hemolytic anemia, and a pemphigus-type skin disorder developed, all of which responded to immunosuppressive therapy. It is not known whether the polysystemic disease in this dog represents a pleomorphic manifestation of canine systemic lupus erythematosus or multiple autoimmune disorders occurring in the same animal.  相似文献

A 7 yr old Labrador retriever initially presented for severe halitosis, mild ptylism, and depigmentation of the nasal planum. Erythema multiforme was diagnosed based on clinical signs and dermatopathology. Treatment was initiated but the condition did not resolve. Six months later, the dog was diagnosed with a mediastinal mass. Trucut biopsy was performed and histopathologic diagnosis was consistent with a thymoma. A median sternotomy was performed, the thymoma was excised, and the dog recovered well. Four months postoperatively, there were no longer any obvious erythema multiforme lesions and the skin condition was controlled without medication. Erythema multiforme may be a paraneoplastic disorder associated with thymoma in the dog, similar to thymoma-associated exfoliative dermatitis in the cat. Clinical signs of erythema multiforme may warrant performing thoracic radiographs or thoracic CT to rule out thymoma as an underlying cause.  相似文献

Megaesophagus, hypercalcemia, and eosinophilia associated with glucocorticoid deficiency were detected in a 5-year-old neutered female Standard Poodle with concurrent hypothyroidism. Clinical and biochemical abnormalities resolved with glucocorticoid replacement treatment, and the dog was normal 29 months after diagnosis. The dog's breed and sex and the existence of a second endocrinopathy supported an underlying immunologic disorder.  相似文献

A 3-month-old male intact Shiba Inu dog was evaluated for a seizure disorder initially deemed idiopathic in origin. Seizure frequency remained unchanged despite therapeutic serum phenobarbital concentration and use of levetiracetam. The dog was documented to be markedly hypoglycemic during a seizure episode on reevaluation at 6 months of age. Serum insulin concentrations during hypoglycemia were 41 U/μL (reference range, 10-29 U/μL). The dog was transitioned to 4 times per day feeding, diazoxide was started at 3.5 mg/kg PO q8h, and antiepileptic drugs were discontinued. No clinically relevant abnormalities were identified on bicavitary arterial and venous phase contrast computed tomographic imaging. The dog remained seizure-free and clinically normal at 3 years of age while receiving 5.5 mg/kg diazoxide PO q12h and twice daily feeding. Seizures later occurred approximately twice per year and after exertion, with or without vomiting of a diazoxide dose. Blood glucose curves and interstitial glucose monitoring were used to titrate diazoxide dose and dosing interval. Congenital hyperinsulinism is well recognized in people but has not been reported in veterinary medicine.  相似文献

Hemophilia A was diagnosed in a mixed-breed female dog with an acute bleeding disorder. Coagulation factor analysis was used to determine low factor VII-coagulant activity in the dog. Hemophilia A is an X chromosome-linked recessive trait that has not been reported as a cause of disease in female dogs.  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

Hepatocutaneous syndrome (HS) is an uncommon skin disorder that occurs in conjunction with liver disease and is diagnosed based on decreased plasma concentrations of amino acids and the histopathology of skin lesions. The survival period generally is <6 months. A 10‐year‐old castrated male Maltese dog was presented for evaluation of lethargy, polyuria, polydipsia, and skin lesions including alopecia, erythema, and crusts. Based on increased liver enzyme activity, low plasma amino acid concentrations, and findings from liver cytology and skin biopsy, the dog was diagnosed with HS. In addition to administration of antioxidants, hepatoprotective agents, and amino acids IV, allogenic adipose tissue‐derived mesenchymal stem cells were infused 46 times over a 30‐month period: 8 times directly into the liver parenchyma guided by ultrasonography and the remainder of the times into peripheral veins. After commencing stem cell therapy, the dog's hair re‐grew and the skin lesions disappeared or became smaller. During ongoing management, the patient suddenly presented with anorexia and uncontrolled vomiting, and severe azotemia was observed. The dog died despite intensive care. On necropsy, severe liver fibrosis and superficial necrolytic dermatitis were observed. The dog survived for 32 months after diagnosis. A combination of amino acid and stem cell therapy may be beneficial for patients with HS.  相似文献

Primary (extranodal) malignant lymphoma limited exclusively to the urinary bladder is an extremely rare disorder in both humans and animals and has to be differentiated from malignant lymphoma cases where a systemic (multicentric) lymphoma has spread to the bladder. We report a case of a 3-year old female spayed mixed breed dog presenting with gross haematuria and dysuria and diagnosed with a primary B-cell high-grade lymphoma of the urinary bladder without involvement of any other site. After treatment with a combination of hypofractionated external beam radiation and cytotoxic chemotherapy, rapid and complete remission of the tumor occurred. At present the dog is alive and has been in remission for 52 months.  相似文献

An approximately 12-week-old, male fox terrier was presented for clinical and physical signs consistent with hydrocephalus. Diagnostic evaluation led to a diagnosis of external hydrocephalus and fibrinopurulent meningoencephalitis. Treatment consisted of antibiotics and the placement of a ventriculoperitoneal shunt. The dog improved neurologically and was alive and doing well 1 year following initial presentation. This is the first reported case of external hydrocephalus in the dog. The dog of this report exhibited clinical features consistent with a disorder termed hydrocephalus with periventricular encephalitis.  相似文献

Fracture and luxation of the second cervical vertebra of a dog were repaired with braided polyester sutures. After 28 months, the dog became ataxic. Compression of the spinal cord at C1-2 was seen on a myelogram. Surgical exploration of the area revealed a granuloma associated with the sutures and compressing the spinal cord. After the granuloma was removed, the dog recovered and has remained neurologically normal for 21 months. The abnormal tissue was determined histologically to be a pyogranuloma.  相似文献

Myelodysplastic syndrome in two dogs   总被引：2，自引：0，他引：2  
Two cases of myelodysplastic syndrome in the dog are described. Both cases were characterized by hepatomegaly, cytopenias, macrocytosis, cellular bone marrow, and dysplastic changes in all hematopoietic cell lines. Serum vitamin B12 and folic acid concentrations were within reference ranges in one dog, but vitamin B12 was slightly decreased in the other. Vitamin B12 therapy did not result in amelioration of the hematologic disorder. The duration of illness was approximately 5 months. Necropsy of one dog revealed an acute undifferentiated leukemia.  相似文献

Basophilic leukemia in a 6-year-old dog was characterized by marked splenomegaly, anemia, and leukocytosis in which 89% of the circulating leukocytes were basophilis. After an attempt at busulfan therapy, the dog was treated with hydroxyurea and was maintained on this drug for 2 months. After withdrawl of hydroxyurea, the dog remained in remission and was still in remission at the time of writing (8 months later).  相似文献

A 5-month-old Maltese was examined because of a holosystolic heart murmur. Results of echocardiography were suggestive of a small isolated interventricular septal defect. Color flow and pulsed-wave spectral Doppler echocardiography confirmed that there was left-to-right blood flow through the defect during systole and diastole. Because of the small size of the defect, the large systolic pressure differential between the ventricles (72.6 mm Hg), and the lack of clinical signs, the small amount of left-to-right shunting was considered clinically unimportant, and no medication or treatment was recommended. Seven months later, the dog was re-examined, and trans-septal blood flow was no longer seen. Isolated interventricular septal defects are a common congenital heart disorder in some breeds of dogs. Such defects may be subclinical in some dogs. In others, they cause a wide spectrum of clinical problems. Findings in this dog suggest that interventricular septal defects may close spontaneously in some dogs.  相似文献

HISTIOCYTIC ULCERATIVE COLITIS IN A BOXER DOG   总被引：1，自引：0，他引：1  
SUMMARY: A 2-year-old male Boxer dog had passed loose faeces mixed with fresh blood and mucus for 8 months. Tenesmus after defaecation was a feature. Colitis was diagnosed from the proctoscopic appearance of the recto-colonic mucosa and confirmed from a biopsy. The disorder proved unresponsive to sulphasalazine therapy, but oral chloramphenicol, betamethasone and prednisolone enemas administered over a 6-week period produced a satisfactory clinical improvement, which persisted for a further 3 weeks without treatment. However, follow-up proctoscopy showed only a marginal improvement in the appearance of the mucosa and appeared to exacerbate further bloody diarrhoea, which persisted. The dog was destroyed and histiocytic ulcerative colitis confirmed at autopsy.  相似文献

Diabetes mellitus and keratoconjunctivitis sicca were diagnosed in a female Poodle. The dog was treated for diabetes and keratoconjunctivitis sicca until blood glucose concentrations were within normal limits. Treatment for keratoconjunctivitis sicca was suspended then, and signs of this disorder did not appear again. Most of the factors known to predispose to keratoconjunctivitis sicca were not applicable to this dog. On the basis of observations made in this dog, we suggest that diabetes mellitus and keratoconjunctivitis sicca may be linked. Clinical signs of the disorders developed simultaneously and resolved when diabetes mellitus was controlled with insulin.  相似文献

A 13-year-old, male cocker spaniel presented with a history of inappetence, depression and reluctance to stand. The dog had multiple, ulcerated skin lesions which were diagnosed as panniculitis by histopathology. A diagnosis of pancreatitis was made on the basis of markedly elevated serum lipase concentrations, abdominal ultrasonography which showed an abnormal lobulated area of hypoechoic tissue in the body and right lobe of the pancreas, and a fine needle biopsy from this area which revealed large numbers of degenerate neutrophils. After treatment with antibiotics and prednisolone, the dog made a full clinical recovery and was free of clinical signs for four months. The dog was euthanased five months later and postmortem examination revealed chronic, active pancreatitis and a pancreatic adenoma. This is the first report of antemortem diagnosis of pancreatitis and panniculitis in a dog.  相似文献

Ileocolic intussusception was successfully treated surgically by partial enterectomy and enteroplication in an 11-month-old, male neutered German shepherd dog. Segmental intestinal volvulus was identified in the same dog two months later and was managed successfully by a second partial enterectomy. The dog made an uneventful recovery and was free of clinical disease six months after the second surgery. Both conditions are reviewed in this case report and a possible relationship between these two episodes in this dog is discussed.  相似文献

Bilateral mandibular defects in a male mongrel dog were repaired. On the left side, a free vascularized coccygeal bone graft that included the median caudal artery and caudal vein was used to correct the defect. On the right side, the defect was bridged with a bone plate and screws. For further immobilization, the muzzle was temporarily taped for 3 weeks and a pharyngostomy tube was used for nutritional support. The dog was able to eat dry commercial food satisfactorily within 2 months of surgery despite mild malocclusion. Radiographs taken 2 months and 18 months postoperatively showed bony union with graft hypertrophy in the left mandible, whereas the right mandibular defect showed protracted nonunion. The results indicate that vascularized coccygeal vertebra transfer provides an alternative for the management of canine mandibular defects.  相似文献

An eight-year-old, spayed female Labrador retriever was presented for evaluation of left thoracic limb lameness. Radiographs of the left elbow revealed mineralization of the soft tissues surrounding the joint, with no evidence of periarticular bony lysis. Biopsy of the synovial tissues of the left radiohumeral joint yielded a diagnosis of osteosarcoma (OSA). The dog was treated with palliative radiotherapy, piroxicam, and carboplatin chemotherapy, which resulted in excellent pain control for approximately eight months. Amputation of the affected limb was then performed. Six months later, the dog developed multiple subcutaneous OSA metastases, and the dog was euthanized 15 months after diagnosis due to refractory vomiting. This report documents the first known case of primary OSA of the synovium in any species.  相似文献
