SPOTTED FEVER GROUP RICKETTSIA RETINITIS IN A TRAVELER TO AFRICA
Bibliographic record
Abstract
In Brief Purpose: To describe a case of rickettsial retinitis in a traveler returning from Africa. Method: Case description. Results: A 67-year-old woman returning from an excursion in the jungles of Africa presented with a 2-day history of floaters and decreased vision in the right eye. In the two preceding weeks, she had experienced fever, malaise, a black eschar on the right elbow, and a rash on her extremities. Examination revealed panuveitis with a solitary, white retinal lesion adjacent to a retinal vessel in the posterior pole of each eye. Extensive diagnostic workup revealed a positive serology for rickettsial antibodies. Her treatment consisted of a course of oral doxycycline. Conclusion: Rickettsial retinitis is an emerging ocular infection in several endemic areas. This case description constitutes the first report of spotted fever group rickettsial retinitis in a traveler to Africa. A 67-year-old woman presented with bilateral floaters, decreased vision, fever, malaise, a black eschar on the elbow, and a petechial rash after a recent trip to Africa. Examination revealed bilateral, white retinal lesions and the serology was positive for rickettsial antibodies, confirming the diagnosis of spotted fever group rickettsial retinitis.

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.
