An Unusual Case of Stroke and Fevers in a Traveler Returning from Arizona
Bibliographic record
Abstract
Primary coccidioidal infection caused by inhalation of spores growing several inches below the surface of desert soil in the San Joaquim valley in southern Arizona and central California is well documented in the literature. Most infections resolve quickly with minimal symptoms, although some individuals develop a subacute process called “Valley Fever”, which is characterized by shortness of breath, chest pain, cough and fevers lasting from weeks to months. Skin manifestations, including erythema nodosum and erythema multiforme may also be present and generally resolve with resolution of the respiratory tract illness. A recent retrospective study found that 6003 adult and 332 pediatric patients were hospitalized with endemic mycosis in 2002, but the overall incidence has been estimated at about 150,000 infections per year. We report a unusual case of recurrent stroke temporally associated with a CNS Coccidiomycosis infection in a traveler to a region where the fungus is endemic.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
