Abstract

fetched live from OpenAlex

Lichen spinulosis is an uncommon, follicular keratotic disorder characterized by asymptomatic clusters of follicular papules with keratotic spines that primarily occurs in children, and rarely in adults. Various treatment options have been reported in the literature, although none are universally effective. Topical roflumilast (0.3%) is a recently approved phosphodiesterase-4 inhibitor first used in psoriasis which has shown reduction in hyperkeratosis in vitro. We report on an adult with symptomatic and recalcitrant lichen spinulosis who achieved significant improvement with the use of topical roflumilast over a 6-month period.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

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.
