Abstract

fetched live from OpenAlex

Trichostasis spinulosa (TS) is a follicular disorder involving the retention of numerous hairs in a dilated follicle, primarily reported in adults. Drug-induced TS and pediatric TS are rarely described in the literature. We report a four-year-old female with an unusual presentation of TS localized in the groin and vulva. Interestingly, the patient's TS seemed to worsen with the introduction of clonidine for her autism spectrum disorder (ASD). The rash improved significantly once clonidine was held, and recurred when clonidine was re-started. This case highlights that TS should be considered in pediatric patients, even in atypical locations, and clonidine may exacerbate TS.

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.

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.
