Summary
A 12‐year‐old Thoroughbred gelding presented with a history of exercise intolerance and inspiratory stridor. Physical examination revealed a blunt crush injury to the ventral neck and underlying trachea of unknown duration. Tracheoscopy revealed a grade 3 tracheal collapse. Surgical management of the case involved placement of extraluminal titanium mesh screens circumferentially around the trachea for complete support. During the period of hospitalisation, the only post operative complication was seroma formation, which resolved with routine care. Follow‐up after 5 years revealed no further evidence of exercise intolerance, inspiratory dyspnoea or stridor. The horse returned to his previous level of work as a show hunter.
A comparison has been made between 393 indigent Missourians with multiple primary cancers of different tissues and 100 with single primary cancer. The 2 groups are sufficiently similar in all features tested (except religious practice) that it is impossible to predict a cancer proneness in any. The findings show that each new neoplasm is best recognized early for most effective salvage. Merging the sites of involvement in the Missouri sample with others from the medical literature resulted in a collection of 4,271 site‐pairings of multiple cancer. These data suggest that, when cancer first appears in certain tissues, some tissues then have a greater, and some a lesser, likelihood of developing second neoplasms if cancer does begin a second time. This information can be helpful in the care of persons who have had cancer if those tissue zones deserving particular attention in follow‐up are emphasized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
