Abstract

fetched live from OpenAlex

BACKGROUND: To establish whether a treatment regimen of silver nitrate cautery and 4 weeks of antiseptic nasal cream is superior to antiseptic cream treatment alone in the management of pediatric epistaxis. STUDY DESIGN: Double-blind randomized controlled trial. SUBJECTS AND METHODS: Children with epistaxis and visible anterior septal vessels were invited to participate. Patients were randomized to receive treatment or control. Treatment patients received silver nitrate cautery, followed by antiseptic cream for 4 weeks. Control patients received sham cautery followed by antiseptic cream for 4 weeks. RESULTS: A total of 109 patients were randomized and results were available for 93 (85%). Of those receiving cautery, 21 (45.7%) of 46 had no bleeding in the 4 weeks before follow-up. Of those receiving only antiseptic cream 14 (29.8%) of 47 had no bleeding. (chi(2) = 2.49; P = 0.114). More children in the active treatment group had an improvement in their symptoms compared with controls (42 of 46; 91.3%) in the treatment group vs 33 of 47 (70.2%) controls (chi(2) = 6.626; P = 0.01; relative risk reduction = 71 percent, number needed to treat = 4.7). CONCLUSION: When using subjective improvement in symptoms as the outcome measure, silver nitrate cautery with antiseptic cream twice daily for 4 weeks appears to give a small but statistically significant benefit when compared to antiseptic cream alone.

Not 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.
