I can't thank you enough to all who responded so quickly and generously with their knowledge and wisdom.
For some reason, I was unable to see that it's a poster. This poster discussed a very rare topic that our doctor is investigating, a similar article was published 30 years ago!
Thank you again for your kind help.
