Abstract
Onychomadesis is characterized by separation of the nail plate from the matrix with persistent attachment to the nail bed and often, but not always, eventual shedding. Onychomadesis has been associated with infection, autoimmune disease, critical illness and medications. To our knowledge a literature review of all associations with onychomadesis has not been completed previously. Most commonly, onychomadesis has been reported in association with pemphigus vulgaris and hand-foot-mouth disease, and following chemotherapy or antiepileptic medications. This article summarizes these key culprit associations, postulates the pathogenesis of nail matrix arrest and summarizes the clinical outcomes. We conducted a retrospective review of cases of onychomadesis reported from January 1960 to March 2013. Using the PubMed database, the literature was searched using the following terms: 'onychomadesis' and 'proximal nail shedding'. Also, an Ovid search was carried out using the same terms. In total 56 articles have been published, including our previously reported series of idiopathic onychomadesis. Articles pertaining only to Beau's lines and not true onychomadesis were excluded. Onychomadesis has been associated with autoimmune disease, other major medical illness, neonatal illness, medication and infection.

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.
