Abstract

fetched live from OpenAlex

Marchiafava-Bignami disease (MBD) is a disorder associated with chronic alcohol consumption and characterized by demyelination and necrosis of the corpus callosum. Patients may have reduced consciousness, psychotic symptoms, apathy, hemiparesis, ataxia and coma. Although some cases of recovery have been reported, the outcome is poor, with disability or dead. We reported a case of a 56-year-old woman with chronic alcoholism admitted to our hospital with impaired consciousness and a history of gait disturbance. On examination, she was in a coma, with increased muscle tone and left arm paresis. Laboratory studies showed a folic acid deficiency and the CT scan was normal. Magnetic resonance imaging revealed lesions in periventricular white matter and the entire corpus callosum with restriction of water diffusion consistent with the diagnosis of MBD. Despite treatment with B vitamin complex, the patient died. Coma and radiological involvement of the entire corpus callosum are compatible with type A MBD and associated with poor prognosis. Although being a rare alcoholism complication, it should not be forgotten since an early diagnosis and prompt supportive therapy may enable a better outcome.

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.
