Effects of Gentian Violet on Refractory Discharging Ears Infected with Methicillin-Resistant Staphylococcus aureus
Bibliographic record
Abstract
OBJECTIVE: To test the efficacy of topical treatment with gentian violet on methicillin-resistant Staphylococcus aureus (MRSA). STUDY DESIGN: Retrospective study. SETTING: Territorial referral centre. PATIENTS: Patients with discharging ears infected with MRSA alone or MRSA and Pseudomonas aeruginosa (PA). INTERVENTION: One percent gentian violet was applied. MAIN OUTCOME: Remission of discharge. RESULTS: Remission was obtained in 44 of 46 ears infected with MRSA, whereas remission was obtained in only 3 of 6 ears infected with MRSA and PA. The minimum inhibitory concentrations (MICs) of gentian violet for MRSA strains sensitive to topical application of gentian violet and strains resistant to this treatment were 0.03 microg/mL and 0.5%, respectively. The MIC for PA resistant to topical gentian violet treatment was higher than 32 microg/mL. CONCLUSIONS: Topical application of gentian violet is a useful option for the treatment of refractory discharging ears infected with MRSA. However, great care must be taken if there is any chance of the gentian violet reaching the middle ear.

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.
