Abstract

fetched live from OpenAlex

The histopathological changes in shunted hydrocephalic children with slit ventricle syndrome have never been described. Periventricular gliosis is presumed to be an important feature. A girl who was shunted in infancy following meningitis developed headaches at 10 years of age and suffered a respiratory arrest, from which she was resuscitated. CT scan of the head showed very small ventricles. A diagnosis of slit ventricle syndrome was made. She died 33 h later. Autopsy revealed a large head and brain, small ventricles with glial adhesions, obstruction of the cerebral aqueduct, complete obstruction of the shunt catheter and reactive astroglia in the periventricular white matter. The latter change was no more severe than in hydrocephalic children with enlarged ventricles who have died following shunt failure. Periventricular astrogliosis may not necessarily be the major determinant of the slit ventricle syndrome.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
