Abstract

fetched live from OpenAlex

ABSTRACT Patients with traumatic head injury and those who have undergone neurosurgery are considered at greater risk for seizures and are routinely given phenytoin for prophylaxis. The author conducted a literature review on the topic of seizure prophylaxis with phenytoin in posttraumatic and postcraniotomy patients. For posttraumatic seizures, phenytoin appears beneficial in preventing only early seizures (defined as occurring up to 1 week after injury). Phenytoin prophylaxis showed a beneficial effect after craniotomy in only one trial. On the basis of the literature review, prescribing guidelines were developed at the author’s institution. Patients with traumatic head injuries and those who have undergone craniotomy receive phenytoin prophylaxis for 7 days after the injury or the craniotomy. Prophylaxis is not given for late seizures; however, anticonvulsant treatment is started if a seizure occurs. RESUME Les patients victimes de traumatismes crâniens et ceux ayant subi une neurochirurgie auraient un risque plus eleve de crise d’epilepsie et recoivent systematiquement de la phenytoine en prophylaxie. L’auteur a passe en revue la litterature traitant de la prophylaxie a la phenytoine des crises chez les patients ayant subi un traumatisme ou une craniotomie. Dans les cas de crises post-traumatiques, la phenytoine semble etre benefique pour prevenir les crises precoces (definies comme celles survenant moins d’une semaine apres le traumatisme). Le traitement prophylactique post-craniotomique a la phenytoine a montre un effet benefique dans seulement un essai. En se fondant sur la revue de la litterature, l’etablissement auquel est rattachee l’auteur a elabore un guide de prescription. Les patients ayant subi un traumatisme crânien ou une craniotomie recoivent un traitement prophylactique a la phenytoine de sept jours suite au traumatisme ou a la craniotomie. Le traitement prophylactique n’est pas prescrit dans les cas de crises tardives. Cependant, un traitement anticonvulsivant est amorce si des crises surviennent.

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.
