Abstract
PURPOSE: To identify the probable etiologies and characteristics of new-onset seizures after orthotopic liver transplantation (OLT) and to assess their clinical implications and prognosis. METHODS: We retrospectively analyzed the clinical, electrophysiologic and laboratory data of 17 patients with new-onset seizures after OLT among 367 adult and pediatric patients who underwent OLT between 1999 and 2001. RESULTS: A suspected etiology of seizures was identified in most patients, including 6 (35.2%) with neurotoxicity due to immunosuppressive therapy, 4 (23.5%) with cerebrovascular disease, 3 (17.6%) with severe metabolic derangement by sepsis or rejection, and 1 each (5.8%) with hyperglycemia and brain edema due to fulminant hepatic failure. Causative factors could not be identified in 2 patients (11.8%). Seizures recurred in 15 patients (88.2%), with 9 occurring on the same day as the original seizure. Attacks caused by neurotoxicity tended to have an earlier onset, within 1 week in 4 of 6 patients, than those caused by cerebrovascular disease and sepsis/rejection, but this was not statistically significant. A total of 21 EEGs were performed in 13 patients. Eleven patients had abnormal EEG findings, of whom 4 (30.7%) showed epileptiform discharges, but the outcome of patients with epileptiform activity did not differ statistically from that of patients without such discharges (p > 0.6). The incidence of poor outcome (death or persistent vegetative state) in the group with seizures was almost 10 times higher than in the group without seizures (52.9 vs. 5.7%, p < 0.001). The prognosis of patients with seizures due to cerebrovascular disease and severe metabolic derangement by sepsis/rejection was poorer than that of patients with seizures caused by the neurotoxicity of immunosuppressive drugs (p < 0.02), suggesting that the underlying cause of seizures is important in determining prognosis. Of 8 patients who survived, 1 was lost to follow-up. The long-term outcome of seizures in surviving patients was excellent, with all survivors available for follow-up being seizure-free for a mean follow-up of 42.5 months (range, 16-58 months). CONCLUSION: New-onset seizures after OLT may herald fatal outcome, especially in patients with cerebrovascular disease or sepsis. The prognosis of seizures in survivors is excellent, and long-term antiepileptic drugs are not required in most cases.

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 it
