Abstract

fetched live from OpenAlex

OBJECTIVE: Here we present a 29 year old male with Parinaud’s Syndrome who is positive for Anti-GQ1b antibody which is highly specific for Miller Fisher Syndrome(MFS) BACKGROUND: Parinaud's Syndrome, also known as dorsal midbrain syndrome is a group of abnormalities of eye movement and pupil dysfunction. It is caused by lesions of the upper brain stem. It is a cluster of abnormalities of eye movement and pupil dysfunction, characterized by: Paralysis of upgaze, Pseudo-Argyll Robertson pupils, Convergence-Retraction nystagmus, and Eyelid retraction (Collier's sign). Miller Fisher syndrome (MFS) is characterized by the acute onset of external ophthalmoplegia, ataxia of a cerebellar type, and the loss of tendon reflexes. Acute onset of external ophthalmoplegia is a cardinal feature. Anti-GQ1b antibodies are prominent in MFS, and have a relatively high specificity and sensitivity for the disease. It is considered a variant of Guillain-Barré syndrome (GBS), because some patients who present with MFS progress to GBS. RESULTS: This is a case report of a 29 year old male who presented with a sudden change in vision. Examination revealed Parinaud’s Syndrome. Given his preceding history of diarrhea along with new onset opthalmoplegia, ataxia, and areflexia, anti-GQ1b antibodies were requested. The resulting titre was positive confirming the suspected diagnosis of Miller Fisher syndrome. Brain imaging showed no lesion or hydrocephalus as cause for patients symptoms. He responded to intravenous immunoglobulins with full resolution of his symptoms and signs. CONCLUSIONS: We present a 29 year old male with sudden onset Parinaud’s Syndrome in the context of ataxia and areflexia. Anti-GQ1b antibody titres were positive which is highly specific for Miller Fisher Syndrome. This is a novel case of Parinaud's syndrome being the presenting symptom for Miller Fisher syndrome.

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.
