Abstract

fetched live from OpenAlex

Hydrogen peroxide poisoning is a rare but potentially severe poisoning that can cause digestive tract irritation and/or gas embolism when ingested. The clinical presentation varies from asymptomatic patients to severe embolic consequences or even death. There is little evidence on the treatment of such poisoning to guide physicians in caring for these patients. This paper reports on two cases of highly concentrated hydrogen peroxide poisoning after accidental ingestion. Both patients showed evidence of portal venous gas, with one patient exhibiting significant symptoms while the other did not. Both were treated with hyperbaric oxygen therapy (HBOT), with a follow-up CT scan revealing a complete resolution of the portal venous gas. This suggests that HBOT is effective for both symptomatic and asymptomatic patients with portal venous gas and should be considered as an effective treatment option in cases of highly concentrated hydrogen peroxide poisoning.

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.

Not 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.
