Acute combined central and peripheral demyelination: a case report
Bibliographic record
Abstract
Aim / Background: We report a case of Acute Combined Central and Peripheral Demyelination (ACCPD). This rare disease presents with features of both peripheral and central demyelination. Methods: Case Report Results: A 24 year-old Iraqi female presented with acute onset of ascending paralysis, numbness and areflexia over the course of a few days. Systemic examination was negative. She responded to IVIG. She suffered two severe relapses over the next three months, which resolved rapidly with PLEX/corticosteroid. CSF was normal after first and second relapses. Brain and cord MRI revealed multiple T2/FLAIR hyperintensities consistent with multiple sclerosis. There were no longitudinally extensive cord lesions. Aquaporin 4 antibody assay is pending. ANA was strongly positive; anti-DSDNA and SS antibodies were negative; complement4 was low and serum cyroglobulins were positive. Hepatitis C was negative. Ganglioside antibody assay was negative. Anti-neurofascin is pending. Neurophysiology confirmed features of an acquired demyelinating neuropathy with profound secondary axonal denervation. Conclusions: The underlying etiology of ACCPD is presumed autoimmune likely secondary to auto-antibody targeting of central and peripheral myelin epitopes. Low complement component 4 and cryoglobulinemia in this patient supports an autoimmune pathogenesis. Neurofascin has been previously reported as one such auto-antibody in ACCPD.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
