Iron Deficiency Anaemia Caused by Nonspecific (Idiopathic) Small Bowel Ulceration: An Uncommon Presentation of an Uncommon Disease
Bibliographic record
Abstract
Ulcers of the small bowel are rare, and in most cases are due to infections, inflammatory bowel diseases, malignancies or drugs. When none of these causes is recognized, they are classified as 'nonspecific' or idiopathic. Such lesions are uncommon, and in most cases present with occlusion. A case of a middle-aged woman with iron deficiency anemia due to occult bleeding, with negative gastroscopy and colonoscopy is presented. The diagnosis of a small bowel pathology resembling Crohn's disease was made by small bowel follow through and small intestine contrast ultrasonography. An ileal ulcer was identified at surgery, and after resection the patient experienced a stable recovery from the anemia without ulcer recurrence. Neither histology nor clinical or biochemical features suggested the diagnosis of an inflammatory bowel disease. Other possible causes were unlikely and the lesion was therefore diagnosed as idiopathic. This report also focuses on the need and the modality to investigate the small bowel in iron deficiency anemia patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
