Abstract

Cytology is commonly used to diagnose lymphoma and leukemia. Frequently, a diagnosis of lymphoproliferative disease can be obtained via cytology, and some of the common subtypes of canine lymphoma and leukemia can have characteristic cytologic features. Flow cytometry is a critical tool in the objective diagnosis and further characterization of lymphoma and leukemia. Features of the immunophenotype, such as expression of certain cell surface proteins or cell size, can provide important prognostic information. This review describes the cytologic features, flow cytometry immunophenotype, and immunophenotypic prognostic information for 6 major types of canine lymphoma and leukemia.

Reversible control of reproduction in tom cats: medical options for manipulating libido and fertility.
This review focuses on the hormonal drugs for controlling reproduction in male cats currently available to feline practitioners. The reversibility of their effects, which is due to temporary suppression of testosterone secretion and spermatogenesis, makes this option appealing for breeders. The different compounds are described.

Intrathecal mepivacaine after general anesthesia is an effective method of equine euthanasia when compared to intravenous pentobarbital.
Previous publications have shown that the risk of scavenger intoxication through consumption of the carcass is low with an intrathecal lidocaine method. In horses euthanized with intravenous pentobarbital, sodium pentobarbital residues were found in compost pile samples up to 367 days after euthanasia with no decrease in concentration, despite complete degradation of soft tissues.

Fibroblastic osteosarcoma in a guinea pig (Cavia porcellus)
The patient presented a hard mass in the right hind limb extending from the proximal portion of the femur, projecting caudally to the proximal tuberosity of the calcaneus, with an increase in temperature, and a marked increase in sensitivity. Disarticulation was performed.

Key Takeaways for Veterinarians from the NAVTA Demographics Survey
Low salary is still viewed as the most challenging aspect of the job, with 39% of respondents ranking this both the top challenge currently and the top projected issue for the next 5 years. One in 3 credentialed veterinary technicians maintains a second job, often full time, suggesting that they need additional income to support themselves and/or their families.
