Case ReportsPolycythemia vera in a cat and management with hydroxyurea.
Polycythemia vera (PV) was diagnosed in a four-year-old domestic shorthair evaluated for hind-limb ataxia, extension of all claws, and difficulty in jumping to elevated surfaces. Mild cardiac hypertrophy also was diagnosed. Initial laboratory evaluation revealed polycythemia (packed cell volume [PCV], 75%) and normal serum total protein (7.5 g/dl). ⋯ Bone-marrow biopsy revealed relative erythroid hyperplasia characteristic of myeloproliferative disease. Clinical signs were controlled with hydroxyurea (12.2 mg/kg body weight) and occasional phlebotomy. Polycythemia vera is an uncommon feline disease, and clinical reports on the use of hydroxyurea to manage the condition in the cat are lacking.

Evaluation of pulse oximeter probes and probe placement in healthy dogs.
Placement of two different pulse oximeter probes, a finger (f) probe and a multisite (s) probe, was evaluated in six healthy, anesthetized beagles. Concurrent arterial blood gas values were compared to determine the most consistent (repeatable) and accurate (compared to calculated hemoglobin saturations) pulse oximeter probe and probe placement sites for subsequent use in awake dogs. ⋯ Values for SpO2 obtained with the s probe demonstrated a significant correlation with SaO2 values (p = 0.014, R = 0.712) compared to the SpO2 values obtained with the f probe (p = 0.108). The best probe placement sites for the clip-on probes in this study were on the lip and tongue using the s probe; however, the ear, tail, and toe may be acceptable sites in awake dogs using a probe which maintains good contact across these vascular beds.
