Association Between Infantile Spasms and Nonaccidental Head Injury
Bibliographic record
Abstract
Infantile spasms constitute a severe epileptic encephalopathy of infancy with poor long-term developmental outcome. Many diverse etiologies have been associated with infantile spasms, but the pathophysiological process is still not fully understood. We describe 2 cases of previously healthy 1- and 3-month-old infants who suffered a nonaccidental head injury with extensive cerebral lesions. Both presented with acute focal seizures rapidly controlled with phenobarbital. Nevertheless, they developed infantile spasms after a latency period of 3-4 months. Spasms were rapidly controlled with vigabatrin. Both children manifested with developmental delay, either exacerbated (case 1) or elicited (case 2) by infantile spasms. Our report highlights nonaccidental head injury as a risk factor for developing infantile spasms following a seizure-free latency period. A better understanding of the pathophysiology linking accidental brain trauma with infantile spasms could lead to more effective neuroprotective strategies. In the meantime, increased awareness and follow-up are warranted.

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.
