Abstract

fetched live from OpenAlex

Granulomatous amebic encephalitis (GAE) is a rare but fatal infection of the central nervous system with a high mortality rate, due to free-living amoebae that are pathogenic to humans and ubiquitous in the environment. In this paper, we report the case of an immunocompetent adult female with no relevant medical history, who presented with acute symptoms resembling a stroke, including altered mental status, slurred speech, brutal proportional right hemiplegia, facial droop and focal to bilateral tonic-clonic seizures, all concomitant with high fever. Subsequent magnetic resonance imaging of the brain revealed diffuse multiple nodular lesions both above and below the tentorium. The initial cerebrospinal fluid (CSF) profile was of no great significance. However, microscopic examination of CSF was able to identify the presence of amoeboid microorganisms and cyst formation, suggestive of a telluric amoeba’s infection. The patient was then treated with a combination of fluconazole and trimethoprim-sulfamethoxazole, but her neurological state continued to decline until she passed away from GAE. In our case report, we highlight the difficulties clinicians encountered in managing this disease, as the clinical and radiological presentation are nonspecific, in addition to the lack of clear therapeutic guidelines after diagnosis. Our findings point up the urgent need for more precise diagnostic criteria and comprehensive treatment protocols to improve patient outcomes.

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.
