Q

In the study, “Iatrogenic Nasolacrimal Duct Obstruction Following Tooth
Extraction in a Cat” what is ‘no’ in the diagram and why is this structure important?

A

‘no’ is the nasolacrimal ostium, this is where the nasolacrimal duct drains into the nasal cavity

Q

In the study, “Iatrogenic Nasolacrimal Duct Obstruction Following Tooth
Extraction in a Cat” the arrow is pointing to what structure and why was it important in this study?

A

The arrow is pointing to the portion of the nasolacrimal duct that is medial to the canine alveolar wall. The authors suspect alveolar curettage caused acute edema and iatrogenic extraluminal obstruction of the nasolacrimal duct.

JVD 2017

A

There were no significant associations between CBC indices and periodontal disease.

Both NLR and PLCRi were significantly higher in in dogs with OT when compared to HD and dogs with PD - this could be an indicator of a tumor associated inflammatory response

A

No conclusions can be made. Small sample size, and multimodal tx approaches make it difficult to determine.

Although important to know that many lesions will resolve on their own or with allergen therapy alone if dogs were asymptomatic (70%).
