Abstract

fetched live from OpenAlex

Morbihan's disease is a rare form of facial lymphedema often associated with chronic rosacea and other skin diseases such as acne. It presents as indurated erythematous plaques in the upper face, which can be challenging to treat. We report a 69-year-old male of Asian background with a 4-year history of facial swelling and redness, unresponsive to prior treatments. After a clinical diagnosis of Morbihan's disease, the patient was treated with oral isotretinoin 10 mg daily, leading to an 80% reduction in symptoms after 9 months. Mild side effects, including cheilitis and xerosis, were well managed. This case highlights low-dose isotretinoin's potential as a therapeutic option for Morbihan's disease. Previous studies have demonstrated the efficacy of treating Morbihan's disease with isotretinoin at high doses between 40 and 80 mg po daily for 12-24 months.

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.
