Abstract
OBJECTIVE: To describe microscopic colitis (MC) and a stepwise approach to its diagnosis and management. QUALITY OF EVIDENCE: MEDLINE was searched from January 1996 to August 2002. Controlled trials were sought, but due to their relative rarity, most articles cited are well designed retrospective studies and reviews. MAIN MESSAGE: Microscopic colitis in both its collagenous and lymphocytic forms is a relatively common and important cause of diarrhea in middle-aged and elderly patients. It usually presents as chronic watery diarrhea. Results of endoscopic and radiologic examinations are normal; specific histologic findings are seen on colonic biopsy. Once the diagnosis is confirmed, we suggest a stepwise approach to therapy. First-line therapies include antidiarrheal agents; second-line include bismuth subsalicylates and budesonide; third-line include cholestyramine and 5-aminosalicylic acid agents. When patients fail to respond to these therapies, oral corticosteroids or immune modulatory therapy should be considered. For severe unresponsive cases, colectomy is the last resort. CONCLUSION: Microscopic colitis is an important cause of chronic diarrhea. Once the diagnosis is confirmed, a stepwise approach to treatment is suggested.

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.
