Abstract

fetched live from OpenAlex

Diverticular Disease-Associated Segmental Colitis is a variant of chronic colitis which is limited to the rectal area, which is associated with diverticular disease. Histologically it can be differentiated from idiopathic colitis with limited inflammation to the segment and sparing the rest of the colon. There is no long term data on the natural history of this entity. This is a prospective fourteen year follow up on 14 patients who presented with recurrent abdominal pain, with bloody mucousy diarrhoea. Patients were referred either from the emergency room of a teaching hospital or from private offices. Investigation included haematological and biochemical parameters, stool cultures including C. difficile toxin. Colonoscopy with multiple biopsies was performed on all patients at admission and repeated at one year and every three years or earlier. Patients who had acute diverticulitis with CT scan finding of abscess or stricture were excluded. Patients who were diagnosed with acute colitis were excluded. All patients were started on Mesalamine and some received intermittent courses of topical 5ASA therapy. There were 9 males and 5 females with a mean age of 53.2±14.5. The mean duration of symptoms was 34.8± 27 weeks. All patients fit the criteria for Diverticular Disease-Associated Segmental Colitis. Endoscopically the mucosa revealed patchy hyperaemic changes without any evidence of ulceration. This involvement was restricted to the segment with diverticular involvement. Histologically the biopsies showed moderate on chronic colitis with moderate gland distortion, mucin loss and lymphoid hyperplasia. The biopsies proximal and distal to the involved areas were reported to be normal. Five patients stopped their medications and relapsed within six weeks, and were restarted on Mesalamine. The mean follow was 10.4 ± 4.2 years. All patients were treated with Mesalamine at a dose of 1220±600mg. three patients underwent resection for persistence of symptoms and remained asymptomatic. Three patients had intermittent flare ups of symptoms. One patients developed severe diverticulitis and perforated. He subsequently died. Diverticular Disease-Associated Segmental Colitis may respond to 5-aminosalicylate with improvement in symptoms. These patients are at the risk of developing diverticulitis and recurrence in symptoms. Although Mesalamine appears to control the symptoms flare-ups are not uncommon. A proper placebo controlled study is needed to ascertain the natural history of this entity.

Not 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.
