A Palomino gelding presented for evaluation of a mandibular fracture and physical examination revealed swelling and excoriation of the skin over the ventral mandible. Upon further examination, malalignment of the incisors was appreciated in addition to instability and crepitance of both the rostral aspect and vertical ramus of the mandible. Radiographic examination revealed a comminuted fracture within the interdental space and fractures of both vertical ramii of the mandible. Under general anaesthesia via tracheotomy intubation, the fractures of the vertical ramii were reduced and compression plating techniques used along the caudal‐lateral border of both ramii for stabilisation. Intraoral tension band wires were used for repair of the interdental space fracture. A type II external skeletal fixator using Steinmann pins and polymethyl methacrylate connecting bars was applied to increase stability. The horse was maintained on broad spectrum antibiotics and phenylbutazone and discharged following 6 days of hospitalisation. Radiographs were taken 10 weeks after surgery and revealed evidence of adequate healing. On follow‐up 20 months later, the horse was reported to have no difficulties eating and was maintaining its bodyweight. This case is unique due to the severity of the mandibular fracture. The authors are unaware of any previous reports of such a severely comminuted mandibular fracture and its successful reconstruction employing multiple surgical techniques. 相似文献

An 11-year-old male Bearded Collie was brought to the Gifu University Animal Medical Centre with a skin mass on the lateral right thigh. Physical examination revealed a 30 × 65-mm oval mass with an alopecic and ulcerated surface. Histopathology of the surgically excised sample confirmed malignant trichoepithelioma. Five months after the surgery, the dog experienced lumbar pain resulting from metastasis to the lumbar vertebrae. Radiation therapy (RT) was performed and it alleviated the lumbar pain. Nine months after the surgery, multiple skin metastases were identified. RT was performed at each occurrence, which reduced the size of each tumour and resulted in a partial response; however, systemic metastasis occurred and the dog died 17 months after the initial surgery. Canine malignant trichoepithelioma is a rare tumour, so an effective treatment has not been determined. Data from our case study indicate that RT has potential for pain control of primary and metastatic malignant trichoepithelioma. 相似文献

Temporary regression of locally invasive polypoid rhinosinusitis in a dog after photodynamic therapy

A 5‐year‐old male cross‐breed dog with chronic rhinosinusitis was presented. Computed tomography (CT) revealed opacities consistent with soft tissue or fluid in the left nasal cavity and frontal sinus. A diagnosis of chronic rhinosinusitis with myxomatous polyps was based on the histology of biopsy samples, so prednisolone treatment was administered for 1 month. Although the clinical signs slightly improved, no changes were observed on the CT images. At 8 months after the initial presentation, the dog was treated with antivascular photodynamic therapy (PDT) using benzoporphyrin derivative monoacid ring A and, 11 days later, CT revealed remarkably decreased soft tissue opacity; the facial swelling and sneezing also resolved. Three additional sessions of PDT were performed at 114, 210, and 303 days after the first PDT because of recurrence of clinical signs. The disease was well controlled for approximately 10 months by antivascular PDT. 相似文献

The effect of daily doses of 5-15 mg of methimazole on the platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT), and proteins induced by vitamin K absence or antagonists (PIVKA) clotting time in 20 hyperthyroid cats was determined. No significant (P > .05) difference was found in median platelet count. PT, APTT, or PIVKA clotting time before treatment compared to median values at 2-6 weeks or > or =7-12 weeks of methimazole treatment. No cat had a prolonged APTT at any time. At 2-6 weeks of methimazole treatment, 1 cat each developed thrombocytopenia or prolonged PIVKA clotting time despite initially normal values. Three cats had abnormal coagulation tests (prolonged PT [n = 1] and PIVKA clotting time [n = 3]) before treatment that fluctuated during treatment. Excluding the 3 cats that had abnormal PIVKA clotting time before treatment, prolonged PIVKA clotting time developed in 6% (1/17; 95% confidence interval, 0-28%) cats treated with methimazole for 2-6 weeks. Seemingly. doses of methimazole commonly used to treat hyperthyroidism in cats do not cause alteration in PT and APTT, and only rarely prolong PIVKA clotting time. Nevertheless, abnormal PIVKA clotting time may explain bleeding tendencies unassociated with thrombocytopenia in methimazole-treated hyperthyroid cats. 相似文献

Standard treatments for canine hemangiosarcoma include surgery and chemotherapy with doxorubicin, but in spite of treatment most dogs with this disease die within 6 months of diagnosis. Tumor growth and metastasis are angiogenesis dependent. Antiangiogenic drugs such as minocycline may provide therapeutic benefits in cancer patients. The purpose of this prospective study was to evaluate the efficacy of chemotherapy with doxorubicin and minocycline, an antiangiogenic agent, in dogs with hemangiosarcoma. Eighteen dogs with histologically confirmed hemangiosarcoma of any stage were treated with doxorubicin, cyclophosphamide, and minocycline. Complete staging was performed before and during the treatment period to assess remission status and response to therapy. No statistically significant difference was found in survival between the dogs treated with chemotherapy and minocycline, and historical controls consisting of dogs that received chemotherapy alone. Postmortem examination revealed widespread metastasis, suggesting that minocycline is ineffective as a single antiangiogenic agent in canine hemangiosarcoma. 相似文献
