Went out to a vernal pool today and saw some crazy toad action

Right Lateral Thoracic Wall Mass From A 10 Year-old, Female-spayed, Golden Retriever.  Approximately

Right lateral thoracic wall mass from a 10 year-old, female-spayed, Golden Retriever.  Approximately six months ago the owner noticed a small, firm swelling on the patient’s right chest.  No doubt it grew with time, as it finally got large enough for the owner to become truly concerned!  The patient is clinically healthy otherwise.

The most prominent feature on the cytology were these gorgeous globules of magenta, streaming material!  In fact, the entire slide was imbued with this color when you looked at it without a microscope.  The substance is most likely matrix produced by cancer cells.  Matrix of this color is commonly observed in chrondrosarcomas.  Occasional malignant spindle-shaped cells were found imbedded in the matrix.

*

Diagnosis:  Chondrosarcoma.  Well , that’s the most likely diagnosis given the location and appearance of the neoplastic cells and matrix!  Other possibilities include a myxosarcoma (which produces a mucous like material!) or osteosarcoma (malignant primary bone tumor).  Chondrosarcomas are often regionally invasive but rarely metastasize.  If the owner is on board with a chest wall resection, the patient will have  a good prognosis :-)

Pain is subtle - we cannot depend on vocalisations or extreme abnormal behaviour to determine if an animal is on pain - animals can cover up pain while going about their daily life. Grimace scales have been found to be reliable indicators of pain (full text available)

Unfortunately, I could not find a clear visual grimace scale for dogs, cats or birds :(  

Which is a shame, because perhaps I could have recognised my own dog’s discomfort for the acute pain it was sooner:

(left: dog in pain. See eyes, tension, cheeks, whiskers, ears compared to the multiple species grimace charts above. right: tired but not in pain dog)

Perhaps my new books that arrived today might have some on dogs at least. There’s this visual blog post of a stressed dog at the vet - stress in the absence of a trigger looks very much like pain.

Here is a small comparative cats, with the link going into more detail. Not a scale but better than nothing:

Bonus round - you can get free A3 posters on recognising pain for Rabbits, Mice and Rats from the National Centre for the Replacement, Refinement and Reduction of Animals in Research. My rabbit specialist vet has the rabbit one!

Thunderstorm From Space

Thunderstorm from space

This photo was taken from the International Space Station during a project to capture photos of clouds. Here a large anvil supercell (some 200 km across) is silhouetted against the limb of our blue orb, revealing clearly the layers of the atmosphere somewhere over northern Australia around 1,500 km from the station, which was then flying over Papua New Guinea.

New neurons (in green) are guided to the neocortex  - responsible for controlling language and movement - not by glial cells, but by a protein called reelin.

Vaccine Infographic By Leon Farrant.

Vaccine Infographic by Leon Farrant.

I often speak with patients who tell me that they do not wish to be vaccinated because they do not see the point, that it is a farce, that it can cause autism (it does not), despite educating and informing them of the reasons behind it. 

In the same way that people who did not grow up during the great wars of the mid-twentieth century have little frame of reference as to what the toll of total war can be, neither can a newer generation of people who have never seen the effects of polio, smallpox, and measles ravage humanity. For many people in the developed world, these are just distant, faded memories captured in the pages of medical textbooks. 

I sincerely hope that the understanding of why we vaccinate does not become lost over time, that people need not fall victim to these preventable diseases; otherwise, the suffering, the challenges, and the research that went into developing these vaccines were all for nothing.

This Bad Little Boy Is Super Rare To Find!!!  This Is A Mitotically Active Cell Present In Peripheral

This bad little boy is super rare to find!!!  This is a mitotically active cell present in peripheral blood circulation from a dog - only the second one I have ever seen!!

As a game, in the diagnostic lab we yell KABLAM! anytime we see a mitotic figure.  The first one to say kablam wins :-P  We should so turn it into a drinking game…
