Pneumomediastinum: A Complication of Synthetic Cannabinoid K2 Use
Bibliographic record
Abstract
The use of synthetic cannabinoid K2 (SCK2) continues to rise. Products are sold in different flavors and mixed with various herbal products resulting in innumerable presenting symptoms. Common presentations are psychomotor activity, dystonia, hypertension, tachydysrhythmia, rhabdomyolysis, and renal failure. We present a 21-year-old woman who was admitted for severe nausea associated with several bouts of vomiting and upper abdominal pain. She had used SCK2 for recreation prior to the onset of her symptoms and she has been using SCK2 regularly for about a year. Chest and abdomen roentgenogram revealed pneumomediastinum. Esophagogram ruled out esophageal injury. She was managed conservatively with resolution of pneumomediastinum. We hypothesize that hyperemesis secondary to SCK2 use can increase the alveolar pressure leading to barotrauma. Although pneumomediastinum is a benign and self-limiting condition, esophagogram should be performed to exclude esophageal perforation which is a potentially life-threatening condition. Awareness of this presentation is important in order to evaluate for complications of barotrauma. J Med Cases. 2016;7(10):455-458 doi: http://dx.doi.org/10.14740/jmc2653w

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.
