Treatment of Nail Psoriasis with Intralesional Triamcinolone Acetonide Using a Needle-Free Jet Injector: A Prospective Trial
Bibliographic record
Abstract
BACKGROUND: Treating nail psoriasis is challenging. Corticosteroid matrix injection with needle is a conventional treatment but pain is often a limitation. OBJECTIVE: Evaluate efficacy and safety of triamcinolone acetonide needle-free injection with the Med-Jet MBX in psoriatic fingernail. METHODS: Seventeen patients were enrolled between January 2012 and January 2013. Four treatments sessions were scheduled every 4 ± 1 weeks. Clinical efficacy was evaluated according to Nail Psoriasis Severity Index (NAPSI) score of target nail differences before and after the treatment. RESULTS: Mean baseline NAPSI score was 6.5 on an 8-point scale (95% confidence interval [CI] 5.652-7.348) and mean final NAPSI score was 2.8 on an 8-point scale (95% CI 1.859-3.741), demonstrating statistically significant treatment efficacy (p = .0007). NAPSI score for target nail from baseline to end of treatment was decreased by 46.25%. CONCLUSION: Treatment with triamcinolone acetonide delivered by Med-Jet MBX is a safe, minimally painful and effective treatment for nail psoriasis.

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.
