Spontaneous Clostridium perfringens Myonecrosis of the Shoulder
Bibliographic record
Abstract
Clostridium perfringens is a rare, life-threatening infection. We present an atypical evolution of spontaneous Clostridium perfringens myonecrosis in a monitored healthy patient. After a head injury, the hemodynamically stable patient became febrile and grew cultures of Clostridium perfringens with no identifiable focus. Antibiotics were initiated. Seventy-two hours after culture results, the patient complained of shoulder pain and imaging revealed periscapular subcutaneous emphysema. Multiple surgical débridements of the necrotic supraspinatus muscle were required to eradicate the infection. The unique features of this patient include the opportunity to (1) follow the progression of clostridial myonecrosis in a healthy patient in a monitored setting and (2) study the extended period of time between positive cultures and the onset of clinical myonecrosis, a feature at odds with the classic rapid progression.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
