One of the most common misperceptions of cataract disease is that it is non-progressive, which unfortunately may create a bias toward conservative treatment options. If left untreated, patients with cataract disease will undergo a continuous degeneration of the lens, and in the latest stages, sequelae such as chronic uveitis, secondary glaucoma and retinal detachment may develop. Complications from surgery are much less likely to develop if surgical treatment is performed early. Continue reading →
Dobermans helped Tufts researchers understand the keys to Canine Compulsive Disorder.
The research team at the Tufts Animal Behavior Clinic has long suspected that canine compulsive behavior has a genetic component. Recently, this suspicion was confirmed with the discovery that a variant of a gene, which codes for cadherin-2, was overrepresented in a sample of Doberman Pinschers
High-Dose Cyclophosphamide Holds Promise for Dogs with Lymphoma
For decades, the cornerstone of treatment for dogs with lymphoma has been chemotherapy employing five drugs: cyclophosphamide, doxorubicin, vincristine, L-asparaginase and prednisone. Efforts to optimize these protocols by adjusting the doses and scheduling of drugs have not yielded significant improvement in remission rates or survival times. In addition, the realization that discontinuous short chemotherapy protocols are as effective as traditional long protocols that include a lengthy maintenance phase has provided the opportunity to search for novel therapies to combat lymphoma before overt chemotherapy resistance develops.
Alternative modalities that have been studied include radiation therapy, chemotherapy agents traditionally reserved for rescue therapy, monoclonal antibodies, dose-intensified chemotherapy and bone marrow transplantation. These approaches have yielded variable results, and some promising findings are under continued investigation. Continue reading →
Clinical investigation of hemostasis in dogs and cats with naturally-occurring disease processes is facilitated by the state-of-the-art equipment housed in the coagulation laboratory at the Foster Hospital for Small Animals at Tufts University. A recent study performed at Tufts (JAVMA: Fenty et al.) used thromboelastography to document hypercoagulability in dogs with immune-mediated hemolytic anemia prior to therapy with prednisone. Certainly this population of dogs is known to experience severe thrombotic complications, at times despite aggressive anticoagulation.
