Radiographic Findings in 20 Patients with Hantavirus Pulmonary Syndrome Correlated with Clinical Outcome
Bibliographic record
Abstract
OBJECTIVE: Hantavirus is a rare rodent-borne pathogen responsible for the Hantavirus pulmonary syndrome. The objective of this study was to review the clinical and radiographic findings of patients presenting with Hantavirus pulmonary syndrome in northern Alberta, Canada. MATERIALS AND METHODS: We retrospectively reviewed the cases of 20 patients who presented with Hantavirus pulmonary syndrome from 1989 to 1999. RESULTS: Two patterns of presentation were identified. One group (13/20 patients) presented with fulminant clinical and radiographic findings and required intensive care support. Six (46%) of the 13 died within a few days of presentation. Some presented in respiratory failure with bilateral parenchymal infiltrates or a rapid progression from mild bilateral interstitial changes to bilateral interstitial and alveolar infiltrates with pleural effusions. The radiographic findings paralleled these clinical symptoms. The second group (7/20) consisted of patients whose clinical course was more limited, as were their corresponding radiographic findings. These patients had a limited hospital stay, and only minimal changes were identified on radiographs. None of the second group of patients died. CONCLUSION: Clearly, in our study, the patients with Hantavirus pulmonary syndrome presented as two groups: those with the fulminant form of the illness and those with the limited type. Of the patients we studied, the group with the fulminant form presented with severe clinical symptoms and radiographic signs of pulmonary disease and had a 46% mortality rate. The group with the limited form presented with mild clinical symptoms and minimal radiographic changes and had no mortalities.

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.
