A case of migraine treatment in a patient with a clinical diagnosis of <scp>CHARGE</scp> syndrome using onabotulinum toxin A
Bibliographic record
Abstract
CHARGE syndrome is a genetic disorder that affects multiple organ and sensory systems. Cranial nerve involvement is one of the key clinical diagnostic criteria. We present the case of an 8-year-old girl with CHARGE syndrome, associated right-sided facial palsy, and chronic severe migraines, that were intractable to medical treatment. At age 6, onabotulinum toxin A was used to weaken the contralateral non-paralyzed side of her face to address her stigmatizing asymmetry. Onabotulinum toxin A chemodenervation was performed on the left lower lip depressors to relax the muscles and improve left lower lip position. Coincidentally, it was noted that with these treatments, migraine symptoms resolved. As the chemodenervation subsided over the next 3-4 months, the severe migraines returned. Continued treatment with onabotulinum toxin A injections every 3 months has resulted in ongoing improvements in facial symmetry and migraine control. Onabotulinum toxin A is a well-known treatment of chronic migraine. Injections are usually directed to the occipitalis, frontalis, and corrugator muscles. The literature has no reports of injections to the lower lip depressors as a useful therapy for migraine, making the results from this case unique.

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.
