|
a. Nonneoplastic nodules are smooth, rounded and often operculated whereas the neoplastic nodules are lobular, cauliflower like and often ulcerated and necrotic. Not diagnostic though and appearance doesn’t always correlate with malignancy 89 |
|
Are CRP levels elevated only in neoplastic nodules

|
Which two medications could be potentially used as they are antibodies for VEGF
|
a. Bevacizumab and kinase inhibitor (sorafenib) 93 |
|
Hemostatic Abnormalities in Uncomplicated Babesiosis (Babesia rossi) in Dogs
What is the most common hematologic hallmarks in dogs with babesiosis |
a. Thrombocytopenia (although clinical bleeding is not common) 94 |
|
What is a well-described consequence of babesiosis
|
a. SIRS 95 |
|
Low platelets can cause what kind of artifact in TEG
|
a. Hypocoagulable indices 96 |
|
TEG performed on dogs that had uncomplicated Babesiosis had what kind of results
|
a. Have normal overall hemostatic function b. Although not out of the reference range and not statistically significant, the k value was negatively associated with platelet count indicating hypocoagulable but this was not observed clinically and still in reference range 97 |
|
Are dogs with babesiosis going to have a tendency to be hyper or hypocoagulable
|
a. Hypercoagulable 98 |
|
What other significant changes were noted among the control and the babesiosis groups
|
a. Babesiosis groups had a higher fibrinogen level and a lower AT level, more prolonged aPTT 99 |
