Abstract
OBJECTIVE: The purpose of this case report is to highlight and emphasize the need for an appropriate and thorough list of differential diagnoses when managing patients, as it is insufficient to assume cases are mechanical, until proven non-mechanical. There are over 250,000 cases of appendicitis annually in the United States. Of these cases, <50% present with classic signs and symptoms of pain in the right lower quadrant, mild fever and nausea. It is standard for patients who present with appendicitis to be managed operatively with a laparoscopic appendectomy within 24 hours, otherwise the risk of complications such as rupture, infection, and even death increases dramatically. CLINICAL FEATURES: This is a retrospective case report following a 27-year-old male with missed appendicitis, who presented to a chiropractor two-weeks after self-diagnosed food poisoning. On assessment, he was tender with resisted lumbar rotation. Psoas Sign, McBurney's Point, vascular exam, hip exam, were negative. A diagnosis of an abdominal strain was provided. Two weeks later, he returned to the chiropractor without an improvement of symptoms. INTERVENTION & OUTCOME: The patient was sent to the hospital, where he was provided a diagnosis of missed appendicitis. He required a hemicolonectomy due to the associated phlegmonous mass. SUMMARY: When a patient presents to a chiropractic clinic with symptoms of abdominal pain, having a comprehensive list of non-mechanical differential diagnoses as well as mechanical differentials is crucial. Appropriate assessment and management of abdominal cases decreases the risk to patients, as missed diagnoses often require more invasive interventions.

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.
