Cerebral Venous Sinus (Sinovenous) Thrombosis in Children
Bibliographic record
Abstract
Cerebral venous sinus (sinovenous) thrombosis (CSVT) in childhood is a rare, but underrecognized, disorder, typically of multifactorial etiology, with neurologic sequelae apparent in up to 40% of survivors and mortality approaching 10%. There is an expanding spectrum of perinatal brain injury associated with neonatal CSVT. Although there is considerable overlap in risk factors for CSVT in neonates and older infants and children, specific differences exist between the groups. Clinical symptoms are frequently nonspecific, which may obscure the diagnosis and delay treatment. While morbidity and mortality are significant, CSVT recurs less commonly than arterial ischemic stroke in children. Appropriate management may reduce the risk of recurrence and improve outcome, however there are no randomized controlled trials to support the use of anticoagulation in children. Although commonly employed in many centers, this practice remains controversial, highlighting the continued need for high-quality studies. This article reviews the literature pertaining to pediatric venous sinus thrombosis.

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.
