Long-term remission and survival in dogs with high-grade, B cell lymphoma treated with chemotherapy with or without sequential low-dose rate half-body irradiation.

Background: Standard of care for dogs with high-grade lymphoma, multiagent chemotherapy, achieves good initial responses but long-term remissions are infrequent; previous studies using half-body irradiation suggest improved long-term outcomes.

Hypothesis: The addition of low-dose rate half-body irradiation would improve outcomes in dogs with B-cell lymphoma.

Animals: Client-owned dogs with stage III or higher, substage a, B-cell lymphoma that achieved complete remission after 4 doses of multiagent chemotherapy.

Persistent reticulocytosis in a case of poodle macrocytosis.

A healthy 14-year-old, male neutered, Miniature Poodle was found to have a persistent erythrocyte macrocytosis and reticulocytosis with a normal and stable HCT. The hematologic features of macrocytosis, increased Howell-Jolly bodies, and metarubricytosis, in the absence of anemia or other cytopenias, combined with the cytologic evidence of bone marrow erythroid dysplasia, including megaloblastosis, binuclearity, increased mitotic activity, and nuclear fragmentation, are consistent with previous reports of congenital dyserythropoiesis termed poodle macrocytosis. We speculate that the additional presence of persistent reticulocytosis in the absence of an identifiable stimulus for accelerated erythropoiesis may represent a phenotypic variation of this inherited condition, and the morphologic abnormalities of the dyserythropoiesis are described.

Safety and Tolerability of Hyperbaric Oxygen Therapy in Cats and Dogs.

This prospective clinical trial was designed to evaluate the safety of hyperbaric oxygen therapy (HBOT) in a population of cats and dogs with a variety of naturally occurring diseases. Seventy-eight dogs and twelve cats with various naturally occurring disease conditions, who had the potential to benefit from HBOT, were enrolled in the study. These patients were treated with HBOT in a monoplace hyperbaric oxygen chamber at 2 air pressure absolute for a treatment length of either 45 min or 60 min.

Ovarian carcinomatosis in a dog managed with surgery and intraperitoneal, systemic, and intrapleural chemotherapy utilizing indwelling pleural access ports.

A 3-year-old Weimaraner dog was presented with bilateral papillary ovarian carcinoma and abdominal carcinomatosis. Treatment included ovariectomy, intraperitoneal cisplatin, and systemic carboplatin. Pleural carcinomatosis 473 days following surgery was treated with intrapleural cisplatin through indwelling pleural access ports.

The diagnosis and management of a case of leishmaniosis in a dog imported to Australia.

This case study discusses in detail for the first time the diagnosis and management of a case of leishmaniosis in a dog imported to Australia. The dog presented with epistaxis and a non-regenerative anaemia five years after being imported from Europe. Protozoa were identified within macrophages in bone marrow and splenic cytology.

Incidence of sterile hemorrhagic cystitis in dogs receiving cyclophosphamide orally for three days without concurrent furosemide as part of a chemotherapeutic treatment for lymphoma: 57 cases (2007-2012).

Objective: To evaluate the incidence of sterile hemorrhagic cystitis (SHC) and other adverse effects in dogs following oral administration of the single-day, maximum-tolerated dose (MTD) of cyclophosphamide divided over 3 days as part of a multiagent chemotherapy protocol for treatment of lymphoma without concurrent administration of furosemide.

Design: Retrospective case series.

Animals: 57 dogs.
