Myocardial perforation by a stick foreign body in a dog
Bibliographic record
Abstract
Abstract Objective: To report a case of myocardial perforation by a stick foreign body in a dog. Case Summary: A 3‐year‐old castrated male Labrador Retriever was examined because of a puncture wound seen after an unsupervised run in the woods. The wound was suspected to penetrate into the thoracic cavity on the basis of physical exam and radiographs. Uniform ventricular premature complexes (VPCs) and junctional beats were noted on electrocardiogram (ECG). Thoracotomy was performed and a 6‐cm wooden stick was seen protruding from the right ventricle through the pericardium toward the sternum. The stick was removed while purse string sutures were tied around the resultant myocardial defect. Follow‐up echocardiography revealed intact intracardiac structures. VPCs were treated with lidocaine and resolved completely within 24 hours of presentation. New or Unique Information Provided: Thoracic trauma can result in myocardial injury; penetration into the myocardium represents a life‐threatening situation for the emergency clinician. Cardiac injury should be included in the differential diagnoses of penetrating thoracic foreign bodies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
