Abstract

fetched live from OpenAlex

Segmental Darier's disease is an uncommon subtype of Darier's genodermatosis, resulting from a mutation in the ATPase type 2 during early embryogenesis. It typically presents as a persistent, pruritic papular eruption following the lines of Blaschko. Histopathology of Darier's disease demonstrates acantholysis, dyskeratosis, and corps ronds. First-line treatment includes topical retinoids, calcineurin inhibitors, and synthetic vitamin D analogues. Severe disease may require systemic therapy with oral retinoids, immunomodulators, magnesium, and low-dose naltrexone. Segmental Darier's disease is important to recognize both clinically and histologically as it may resemble other acantholytic Blaschkolinear dermatoses and should be considered in individuals presenting with a chronic localized papular eruption in a Blaschkoid distribution. Herein, we present a case of a 48-year-old male with segmental Darier's disease who improved significantly following acitretin treatment.

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.
