Abstract

fetched live from OpenAlex

BACKGROUND: Facet-mediated neck pain following motor vehicle collision is a common component of whiplash-associated disorder. Facet-mediated neck pain is suspected based on a combination of history, physical examination, and imaging findings. Third occipital nerve (TON) and cervical medial branch radiofrequency ablation (RFA) are effective and safe approaches to facet-mediated pain. Serious complications are rare but can include nerve root, spinal cord, and vascular injury. CASE REPORT: This report describes a case of subarachnoid hemorrhage (SAH) that occurred within 24 hours following TON and cervical medial branch RFA. The patient was admitted for symptom management, blood pressure control, and follow-up imaging. His hemorrhage stabilized, and he returned home without residual deficits after 12 days. CONCLUSIONS: This case serves as an example of how prolonged nausea, headache, and ataxia can be indicators of SAH, following TON and cervical medial branch RFA.

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. 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.
