Septic arthritis due to<i> Mycoplasma orale </i>in a young patient with hypogammaglobulinemia
Bibliographic record
Abstract
Mycoplasma orale is an obligate intracellular bacterium usually found as a commensal in the human oral cavity. Symptomatic infections with this organism are rare, but severe disease has been described in the setting of impaired humoral immunity. Here, we describe a case in which M. orale was identified from the joint fluid of a patient with septic arthritis, splenic lesions, and agammaglobulinemia. A 15-year-old boy was admitted to the hospital with fever, progressive left knee swelling, and pain. His medical history was significant for Burkitt’s lymphoma, the treatment of which had included rituximab 6 years earlier. M. orale was identified in the synovial fluid using 16S ribosomal RNA gene sequencing. He was also found to be hypogammaglobulinemic, and imaging revealed multiple splenic lesions. He was treated with doxycycline and intravenous immunoglobulin, which resulted in complete resolution of his arthritis and other symptoms. Mycoplasma species should be suspected in patients with humoral immunodeficiency and compatible findings.

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; a candidate call from one teacher head, not a consensus.
