Abstract

fetched live from OpenAlex

A consecutive series of 45 cases of diastematomyelia in adults is analyzed. The majority of patients were females with a 3.4:1 female to male ratio. The ages ranged from 19 to 76 with a mean of 37.8 years. The lesion was usually located in the lumbar region. In 17 patients the development of symptoms was associated with specific incidents or events, usually trauma. Twelve patients had pre-existing static musculoskeletal or neurologic abnormalities and 20 had cutaneous spinal lesions suggesting dysphraphism. The symptoms and signs included pain and a variety of sensorimotor and/or sphincteric abnormalities. Metrizamide CT scanning proved to be the most useful diagnostic procedure. Only 4 patients were investigated by MRI and from the information available its role in the diagnosis of adult diastematomyelia is not established. Twenty-three of 24 patients treated by surgery showed marked improvement.

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.

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.
