Rhinoscleroma: A French National Retrospective Study of Epidemiological and Clinical Features
Bibliographic record
Abstract
BACKGROUND: Rhinoscleroma (RS) is a rare, chronic, granulomatous disease of the upper respiratory tract that is associated with infection with Klebsiella rhinoscleromatis. RS is more common in certain geographic regions than in others, but other risk factors and the pathogenesis of RS remain unclear. METHODS: We sent a standardized questionnaire to all pathologists and otolaryngology specialists in French University Hospitals and asked whether they had seen patients with RS in the previous 16 years (1990-2005). We then retrospectively reviewed the files of all patients identified. RESULTS: We collected 11 cases of RS, with a median patient age at diagnosis of 35.7 years (range, 5-72 years). The 3 patients with a familial history of RS presented with early-onset forms of RS; 1 had an uncommon aggressive presentation of the disease with ischemic stroke. Two unrelated consanguineous families were identified, 1 of which included 2 affected siblings. Two patients with sporadic disease were positive for HIV infection. All patients were living in France, but most were immigrants from areas where RS is endemic (North Africa, 3 of the 11 patients; West Africa, 4 patients; and Turkey, 1 patient). The probable duration of exposure to K. rhinoscleromatis in endemic areas varied widely: 0-28 years. Clinical features and outcome also varied considerably among cases. Biopsies had been performed for all patients and revealed granulomas containing Mikulicz cells. Cultures of biopsy tissue were positive for K. rhinoscleromatis in 5 of the 11 cases. Prolonged antibiotic treatment was administered to all patients, as follows: ciprofloxacin (7 patients), third-generation cephalosporins (2), tetracycline (2), and clofazimine (2). Eight of the 11 patients did not experience relapse during extended periods of follow-up (1.3-12 years). Relapses in 3 patients were confirmed by a second biopsy. CONCLUSIONS: The occurrence of early-onset RS in multiplex and/or consanguineous families suggests that genetic control of the host response to K. rhinoscleromatis may be involved in the pathogenesis of RS in endemic areas.

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.
